Application filed January 2, 1918. Serial No. 210,008.

To all whom it may concern:

Be it known that I, JAMns E. DAVIS, a citizen of the United States, residing at Salem,

in the county of Columbiana and State of Ohio, have invented certain new and useful Improvements in Receptacle-lVashing Machines; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention has for its principal object to provide a simple and inexpensive machine for thoroughly washing cuspidors and other receptacles without touching them with the hands.

In carrying out the above object, a further object is to mount the receptacle support so that it may be tilted to discharge the washing liquid from the receptacle after washing of the latter; and this tilting requires means for tightly holding the receptacle in place, a further object of my invention, therefore being to supply this need.

Yet another object is to so mount the cleaning element as to permit it to rotate either concentrically or eccentrically, for thoroughly washing both the bottom and the sides of the receptacle, and in this connection a still further object is to provide for relative adjustment of the receptacle support and the cleaning element so that both the upper and lower portions of the receptacle may be thoroughly washed.

With the foregoing general objects in view, the invention resides in the novel features of construction and unique combinations of parts to be hereinafter fully described and claimed, the descriptive. matter being supplemented by the accompanying drawings which form a part of this specification and in which:

Figure 1 is a side elevation of the improved machine;

Fig. 2 is an additional elevation of the side of the machine shown at the left of Fig. 1;

Fig. 3 is a vertical section on the plane of the line 33 of Fig. 2;

Fig. 4 is a view similar to Fig. 3 but indicating the cleaning element mounted for retation eccentrically and also illustrating the receptacle support in an inverted position;

Fig. 5 is a horizontal section on the plane I 10 will be held in vertical pos tion to preiindicated by the line 5-5 of Fig. 3;

Fig. 6 is a perspective view of the recep tacle support; and,

Fig. 7 is a perspective view showing more particularly the motion limiting and locking means for the lever which is employed for normally holding the receptacle support or platform against tilting.

In the drawings above briefly described, the numeral 1 designates a suitable type of supporting frame whose structural details form no part of the present invention and need not therefore be described. It is essential, however, that this frame be provided with a pair of vertically disposed guides 2 which may well be formed of vertical bars having slots 3. The guides 2 are located on opposite sides of the frame and a horizontal platform t is positioned between said guides for siiipporting the receptacleR to be washed. Platform 4; is provided with oppositely extending trunnions 5 and 6 which are received in the slots 3, both of said trunnions having rectangular heads 7 which prevent endwise shifting of the platform by abutting the outer sides of the guide bars 2.

The outer end of trunnion 6 is provided with a hand crank or the like 8 for tilting the platform 4 when required, but in order to normally hold this platform against such tilting, the head 7 of the other trunnion is received in a slot 9 formed in a preferably vertical-hand lever 10, said lever being fulcrumed at its lower end to the frame as shown. at 11. When lever 10 is in the position of Figs. 1, 2, 3, 5 and 7, the platform is held against tilting, but when said lever is shifted outwardly to the position indicated in Fig. 4-, said platform may turn as required. To limit the outward movement of lever 10 and to hold this lever in operative position, a link or rod 12 is pivoted thereto and slides through one or more eyes 13 on the frame 1, the end of said rod opposite the lever being bent upon itself at 14: to provide a hook for engagement with one of the eyes to limit the outward movement of the lever, said rod being bent laterally as shown at 15 after forming the hook, to provide an arm for detachable engagement with a pin or any suitable keeper 16 rising from a portion of the frame. This arrangement is most clearly shown in Fig. 7 and from this figure it will be obvious that when the arm 15 and the keeper 16' are in operative relation, the lever vent tilting of the platform 4. When, howany other preferred device could well be employed. The platform 4 is movable upwardly toward the mop to position the latter in the receptacle R for washing purposes, and is movable away from said mop to per- 't i {f of the receptacle to discharge the a.,hi..g liquid therefrom. This upward and downward adjustment of the platform is ermitted by reception of the trunnions 5 d 6 in the slots 3, and for holding said platform upwardly in operative relation with the mop, removable pins 20 preferably extend across said slots beneath said trunnions as will be clear from Fig. 3. These pins are receivable in vertically spaced openings 20 in the bars 2 and when the platform is held in completely raised position, its bottom may be washed, while lowering of said platform to a suitable extent and the shifting of the op 19 to an eccentric position yet to be described. will permit washing of the upper edge of the receptacle wall, the lower portion of such wall being cleaned by shifting the mop to said eccentric position without owerin he platform. Then the platform is lowered to the maximum as shown in Fig. 4. the lever 10 may be releasedand said platform then tilted by means of the crank 8 so that the washing liquid will be discharged from the receptacle previously operated upon by the mop 19.

The mop 19 is provided with an upstanding shank 21 preferably forked at its upper nd and pivoted at 22 to the lower end of he erical drive shaft 23. A removable pin H is provided for holding the shank 21 either in line with shaft 23 to cause concentric rotation of the mop, or for holding sa i d shank and shaft in angular relation as depicted in Fig. 4, thus causing eccentric ro- '"tlOl of the mop for washing the sides of he cuspidor or the like. For driving shaft 23 bevel gears 25, a shaft 26,. and a hand crank 27 are preferably employed, although any other preferred operating means could well be utilized.

For the purpose ofholding the receptacle upon the platform 4, numerous arrange- "entscould of course be employed, but for "llu 'trative purposes I have shown the fol- 'owing: A'pair of posts 28 and 29 rise from opposite ends of the platform .4 to receive theroceptacle therebetween, the post 28 'being formed with a pair of openings 30 spaced apart vertically while post 29 is formed with a vertical notch 31 having keeper-teeth 32 along its opposite sides. A pair of outwardly bowed rods or wires 34 are adapted to have one end passed through either opening 30 as will be clear from Fig. 5, the intermediate portions of said rods embracing the receptacle, while the other ends thereof are received in the notch 31 and engage with the keeper teeth 32. Other rods 35 are provided for holding the receptacle in contact with the platform, said rods passing over said receptacle and having one end received in openings 36 along the edges of the post 28, the other ends of said rods being engaged with keepers formed by lateral lugs 37 which extend from the upper end of post 29.

In addition to the holding means above described, apair of smaller posts 38 preferably rise from the platform and support the ends of one or more wire rods 39, said rods limiting the lateral movement of the receptacle when the latter is being placed upon 90 the platform. Also, this platform may be provided with a plurality of openings 40 disposed at suitable locations for receiving appropriate pegs or the like, such pegs being instrumental in holding differently shaped and sized cuspido s and the like upon the platform 4. V

In operation, the cuspidor orother'receptacle to be cleaned is secured uponthe platform 4 while the latter is in lowered position, said platform being then'raised to position the mop 19 in said receptacle and being supported in such position by the pins or the like 20. The lever 10 is swung inwardly and locked by the rod '12 to prevent tilting of the platform and the crank 27 is then rotated. It is of course understood that either before or after placing the-receptacle upon the platform, a suitable quantity of washing liquid in placed in said recep tacle. With. the parts positioned as shown in Fig. 3, rotation of the mop by the crank 27 and the other driving fmeans, will thoroughly clean the bottom of the receptacle, and when this is done, the mop may be swung to the eccentric. position shown in Fig.4 so that the side of the receptacle may be cleaned around its lower,.edge portion. This having been done, the platform may be lowered and thus the upper portion of the side wall may be cleaned. When the cleaning operation is completed, thelever 10 is swung outwardly and the platform 4 is inverted by means of. the crank 8 to discharge the liquid from the cleaned receptacle (see Fig. 4). This having been done, the platform is returned to'normal position, the receptacle is removed .andanother secured in place to be cleaned. p f

The'machine is rather simple and there fore may be manufactured at small cost, yet it will be highly efficient and durable. Since probably the best results are obtained from the several details shown and described, these details are preferably employed, but within the scope of the invention as claimed, numerous minor changes may well be made.
